PHP表单帖子被调用两次

我有一个表单发布到声明的同一页面。问题是它在提交时似乎被调用了两次。这是代码:

function user_data_form() {

    add_ajax_validation();

    // Form verication start
    if (isset($_POST["action"])) {
        switch($_POST["action"]) {
            case "validate_form":
                ajax_validate();
                break;
            case "update_user_data":
                $wp_user_object = wp_get_current_user();
                $id = $wp_user_object->ID;
                if ( 0 == $wp_user_object->ID ) {
                    redirect(get_permalink(get_page_by_title( 'Sign in' )), array(
                        "message" => 8
                    ));
                } else {
                    $form_data = array(
                        "verified" => false,
                        "email" => $_POST["email"],
                        "first_name" => $_POST["first_name"],

                        "password" => $_POST["password"],
                        "old_password" => $_POST["old_password"],
                        "verify_password" => $_POST["verify_password"]
                    );
                    $form_data["verification"] = array(
                        "old_password" => wp_check_password($form_data["old_password"], $wp_user_object->user_pass, $id),
                        "email" => validate("email", $form_data["email"]),
                        "password" => validate("old_password", $form_data["old_password"]),
                        "verify_password" => validate("verify_password", $form_data["old_password"], $form_data["verify_password"])

                    if ($form_data["verification"]["old_password"]) {

    return $form;
}

问题是invalidate_email()被调用了两次。虽然它只应在$_POST["action"] == "update_user_data"时触发,而invalidate_email()只应在提交表单之后触发。我无法确定第二个电话的来源。

这是我的function invalidate_email($user_id, $new_email) { $key = createKey($new_email); $activation_url = get_permalink(get_page_by_title( 'Activate' ))."?key=".$key."&id=".$user_id."&type=email"; update_user_meta($user_id, 'new_email', $new_email); update_user_meta($user_id, 'email_activation_key', $key); $expires = get_metadata("user", $user_id, "email_expires", true); if (!$expires) { $expires = time() + 86400000; //86400000 milliseconds = 24 Hours update_user_meta($user_id, 'email_expires', $expires); } $message = "A request to update your email for your account on First steps has been made, please confirm your email address by clicking the following link: <p />"; $message .= "<a href='".$activation_url."'>".$activation_url."</a> <p />"; $message .= "If you did not request the change your account may be comprimised and we recommend you change your password from the 'my account' page. <p />"; $message .= "If you do not confirm your new email address within 24 hours the request will expire and you will have to request a new one."; email($new_email, "First steps - Confirm your new email address", "Confirm email address change", $message); } 功能:

email()

function email($to, $subject, $heading, $message, $attachments = NULL) { $headers = array('From: First steps <info@rcnhca.org.uk>', 'Content-type: text/html'); $body = '<table width="100%" style="background:#ECECEC;" cellpadding="0" cellspacing="0"> <tr width="100%" style="background: #3393b5;"> <td align="center"> <table width="500" cellpadding="0" cellspacing="0"> <tr> <td align="center" style="height:45px; vertical-align:middle;"> <a href="'.get_bloginfo("url").'"><img alt="First steps for health care assistants" src="'.get_stylesheet_directory_uri().'/library/images/logo.png" width="347" height="32" style="vertical-align:middle;display:block;" /></a> </td> </tr> </table> </td> </tr> <tr> <td align="center" style="padding: 10px 0px;"> <table width="500" style="padding: 10px;background:#FFFFFF;border:1px solid #BCBCBC;margin:0px 10px;" cellpadding="0" cellspacing="0"> <tr> <td style="color:#000000;font-size:14px;line-height:1.5em;text-align:left;"><font face="verdana"> <h2 style="margin-top: 0.1em; font-size: 18px; padding-bottom: 0.5em; color: #333333; border-bottom: 1px solid #CCCCCC; margin-bottom: 0.7em;">'.$heading.'</h2> '.$message.' </font></td> </tr> </table> <table width="500"> <tr> <td style="font-size:12px;line-height:1.5em;text-align:left;"><font face="verdana">We are committed to keeping your email private, we do not share your address with third-parties.</font></td> </tr> </table> </td> </tr> </table> '; wp_mail($to, $subject, $body, $headers, $attachments); }

add_ajax_validation()

我很肯定它不是Ajax调用(所以忽略HTTP_X_REQUESTED_WITH),因为即使我删除了Ajax验证(这是这个函数的作用),它也会发生。我还检查了应该存在的debug_backtrace()的存在,因为我的所有Ajax都是由jQuery执行的,标题应该存在。

编辑:回复@Oli

我执行了$trace= debug_backtrace(); $funcs = array(); foreach ($trace as $func) { array_push($funcs, $func['function']); } $funcs = implode('\n', $funcs); 以查看调用该函数的内容,这是我的回溯:

invalidate_email
user_data_form
call_user_func
do_shortcode_tag
preg_replace_callback
do_shortcode
pre_process_shortcode
call_user_func_array
apply_filters
wp_trim_excerpt
call_user_func_array
apply_filters
get_the_excerpt
require_once 
load_template
locate_template
get_header
include
require_once
require

输出1:

invalidate_email
user_data_form
call_user_func
do_shortcode_tag
preg_replace_callback
do_shortcode
pre_process_shortcode
call_user_func_array
apply_filters
the_content
include
require_once
require

输出2:

call_user_func()

add_shortcode('user_data_form', 'user_data_form', 134);及以后,这是由WordPress CMS完成以下函数调用的结果:{{1}}

3 个答案:

答案 0 :(得分:0)

调查var_dump(func_get_args())以调查并检测您在invalidate_email函数中收到的参数。

答案 1 :(得分:0)

我之前用mail()注意到了这一点。当你在header部分有一个“To”和mail()的第一个参数中的“to”变量时,它会被发送两次。您可能想删除标题的部分并尝试使用。

应该仔细阅读这个问题。

答案 2 :(得分:0)

我觉得这样一个nincompoop但我只是意识到这是自我造成的。我有这段代码试图避免WordPress的自动格式化函数wpautop。它似乎会解雇他们两次。

function pre_process_shortcode($content) {
    global $shortcode_tags;
    // Backup current registered shortcodes and clear them all out
    $orig_shortcode_tags = $shortcode_tags;
    $shortcode_tags = array();
        add_shortcode('registration_form', 'registration_form', 134);
        add_shortcode('login_form', 'login_form', 134);
        add_shortcode('user_data_form', 'user_data_form', 134);
        add_shortcode('activation_code', 'activation_code', 134);
        add_shortcode('logout_code', 'logout_code', 134);
        add_shortcode('reset_password_form', 'reset_password_form', 134);
    // Do the shortcode (only the one above is registered)
    $content = do_shortcode($content);
    // Put the original shortcodes back
    $shortcode_tags = $orig_shortcode_tags;
    return $content;
}

add_filter('the_content', 'pre_process_shortcode', 13);

我将此更改为:

    add_shortcode('registration_form', 'registration_form', 134);
    add_shortcode('login_form', 'login_form', 134);
    add_shortcode('user_data_form', 'user_data_form', 134);
    add_shortcode('activation_code', 'activation_code', 134);
    add_shortcode('logout_code', 'logout_code', 134);
    add_shortcode('reset_password_form', 'reset_password_form', 134);

这当然会产生其他问题,但至少它解决了这个问题,我会找到另一种方法来做我想做的事情。对于那些花时间尝试解决这个问题的人来说,对不起,因为你从来没有从我提供的信息中解决这个问题。
